Kubernetes is a platform for running containers at scale. It’s open-source and standardised, so you can deploy the same app on AWS, Azure, in the data centre and on your laptop. Kubernetes gives you a language to define how your containerized apps should run, and a clustered platform to run them. Kubernetes is everywhere but it’s a complex system with a steep learning curve. Join Elton Stoneman, Docker Captain and author of Learn Kubernetes in a Month of Lunches for an introduction to the key Kubernetes concepts and tools.
